Customized Metal Platinum Black Catalyst Platinum Nanopowders
Platinum is one of noble metals, it is one of the best catalyst and antioxidants, nano platinum ( Pt ) with small particles size, strong, safe, stable, reliable, environmentally friendly, non-toxic, tasteless, harmless, can be widely used in biomedical, Catalytic industry, cosmetic etc.
1. Platinum Nanopowders for biomedical
Hydrogen and nano-platinum have a synergistic effect that can be used in conjunction with the treatment of oxidant stress disorders; Studies have shown that platinum nano particle-mediated photo-thermal effect in the treatment of bone metastases in nude mice can be a good inhibition of bone tumor growth and osteolytic bone destruction; Lactic acid bio-sensor based on nano - platinum black modification for rapid detection, etc.
2. Platinum Nanopowders as catalyst
Nano platinum are widely applied in catalyst part, Nano-platinum powder has excellent bio-catalytic activity, it can be applied to polymer hydrogenation, reduction and synthesis. Nano platinum also can be used as fuel cell catalyst, due to its high cost, due to its high cost, now some use nano nickle to replace the platinum, and some are looking for ways to improve nano platinum efficiency as catalyst in fuel cells to save cost. Last year Chinese researches have developed a superfine platinum nanowire catalyst on the surface of the zigzag, greatly increasing the surface activity and specific surface area of the fuel cell catalyst, increasing its overall catalytic activity by more than 50 times.
3. Platinum Nanopowders for cosmetics
Platinum nanoparticles , due to its strong oxidation resistance Platinum can effectively remove free radicals in the human body. Play the anti-aging effect and at the same time to achieve whitening bright.
Platinum Nanopowders can also be used for food preservative, car exhaust purification, etc. Nano platinum do have a lot of amazing functions, we cannot list its amazing functions one by one though.

HW nano material sale high purity bi2o3 nano bismuth oxide for electronic ceramics and piezoresistor use
O765: Nano bismuth oxide, particle size 20-30nm,99.5%
O766: Nano bismuth oxide, particle size 30-50nm,99.5%
Bi2O3 nano bismuth oxide is an important functional material. The use of bismuth oxide is not only a good catalyst for organic synthesis, ceramic coloring agents, plastic flame retardants, pharmaceutical astringents, glass additives, high refractive glass and nuclear engineering glass manufacturing and nuclear reactor fuel, but also is a kind of important doping powder material in the electronics industry.
Bi2O3 nano bismuth oxide powder is mainly used in the chemical industry (such as chemical reagents, bismuth salt manufacturing, etc.), the glass industry (mainly used for coloring), the electronics industry (electronic ceramics, etc.) and other industries (such as fire paper manufacturing, nuclear reactor fuel. Among them, the electronics industry is the most widely used bismuth oxide industry, mainly used in varistors, thermistors, zinc oxide arrester and CRT, and other fields. If the material from the points, bismuth oxide is mainly used for electronic ceramic powder materials, electrolyte materials, optoelectronic materials, high-temperature superconducting materials, catalysts. Electronic ceramic powder materials the field of electronic ceramics are a mature and dynamic field for the application of bismuth oxide.
Bismuth oxide as an important additive in the electronic ceramic powder material, the purity of the general requirements of more than 99.5%. The main application targets are three categories that are zinc oxide varistor, ceramic capacitors, and ferrite magnetic materials. In the development of electronic ceramics, the United States is one of the top one in the world. While Japan relies on mass production and advanced technology to occupy the world's ceramic market share of 60%. With the nano bismuth oxide research and development and homogenization of manufacturing technology innovation will also greatly promote the electronic ceramic-related components to improve performance and reduce production costs. Bismuth oxide in zinc oxide varistor mainly plays a role in the formation of agents, zinc oxide varistor with high nonlinear voltammetry, the characteristics of the main contributors.

HW NANO Bismuth oxide powder, 20-30nm,99.5%, yellow solid powder
Nanometer bismuth oxide powder is an important functional material, and is widely used as excellent organic synthesis catalyst, ceramic coloring agents, flame retardant plastics, pharmaceutical astringents, glass additives, high refractive index glass and glass manufacturing nuclear engineering and nuclear reactor fuel, and also is an important dopant in the electronics industry.
Nanometer bismuth oxide with the properties of the general size and due to the finer granularity, Bi2O3 nano particle can be used to inorganic pigments, optical materials, electronic materials superconducting materials, special functional ceramic material, a cathode ray tube wall paint and so on.
Also the Bi-based composite oxide is a good photocatalyst which uses solar energy to eliminate pollutants. To protect the environment, maintain ecological balance, to achieve sustainable development contributes a lot. Bi-based composite oxide due to its unique physical properties can be used as an ion conductor, sound and light materials, light conductors, gas sensors, and photocatalysts.
